Pengu Yu, in case somebody above has failed to make it adequately clear to you, nobody owns Wikipedia's articles and if you think there is something wrong you are encouraged to change it--if someone disagrees they'll either change it back or start a discussion on the talk page.
See this editing guideline page and read it thoroughly up to but not including the section "Non-article namespaces".

And be bold!
